' 'Application filed lily 10,1898. Serial No. 680,293. (No model.)

To all whont it may. concern:

Be it known that I, TONY DAVID, a citizen of the Republic of France,residing-at Lyons,-

France, have invented certain new and use-,

ful Improvements, in, Self-Acting Reading, (for which I have obtainedPatent in France, deposited October 22, 1897, granted February 5, 1898,No. 271,548,) of which the following The features of the invention willbe particularly' described hereinafter and pointed out in the claims.

constructed A, in which the different zones are marked by Z Z Z Z. \Vehave supposed the zones being composed of unbroken surfaces in order tomake the explanation easier.

' This pattern is fixed upon a wain B, running in a parallel directionto thatofthe warp," by 1 means of a screw 0, acted by a ratchet-wheel C,that makes the wain advance every time for aquantity corresponding to astroke of weft.

Upon the pattern A and in the direction of the'weft a comb 'F is placed,of which the metallic teeth, thoroughly isolated amongthems'elves, holdthe place corresponding to the threads ofwarp. Y

The teeth of the comb F are respectively bound together by theconductors G to a set of electromagnets E E, acting,.as furtherexeplicated, on the needles of the jacquard J, which. rules the punchingof. the cartoons. All the electromagnets E are from other partcommunicating by a similar conductorH with one of the poles of thepile'P. The other pole of the same pile is in communication with .acommntator D, which one, .by the means of contact-pieces I I I I,sends'forth at will the current to one of the zones Z Z of the pattern.This above so explained, it must be understood the comb F by itsoccupying the place of any whatever stroke of'weft and the.

. gi'ate R.

piece I the current will only pass through I the teeth of the comb lyingon the 'zone Z of be turned on the contact 1 the current will 1 onlypass through the teeth of the comb lying on the zone Z and through thecorrespond ing electromagnets, and .so on. Therefore it will bepossible'on every stroke of weft to put successivelyand separately atwork the needles of the jacquardcorresponding'to'the. diflrerent colorsortyi ngsupcomposing the said stroke. 1 .flhe jacquard punching thecartoons. The needles Kof this jacquard could be acted by the electro-'termediate apparatus standing ahead of the jacquard and com posed of aset of needles 13,

concording with the needles K and apart connected with an equal numberof small and very light pendulums. M,"-the lower part of J commandmbymeansal ready known, the punches of the machine which serves as armatureto the electromagnets E. When in rest, the pendulum's M mpose by acranked part on the bars of a horizontal grate N, which receives at the"requested time an ascending movement by means of a cam O. Thoseof thep'endulums M, which are drawn by their electromagnets,

. escape the grate and stay in place','as well. as

their needles L, while. the others are rising up and raise'at the sametime their own needles L. A vertical grate R, the voids of which.

are in front of the needles L at rest, pushes aside these ones among thesaid needleswhich have been raised, as well as the corresponding needlesof the jacquard J. 'It re sults from such'an arrangement that theelectromagnets crossed by the current attract their pendulums M and leadthem away from the power of the grate N. The corresponding needles L andK are standing, and correspond ing holes of the jacquardJ are raised upby .the claw S and dermine corresponding holes are punched into theoartoon in' work. The inactive electromagnets, on the contrary,leavetheir 'pendulums M standing. These ones are raised up by the grate N,together with their needles, which then are pushed back by thehecorresponding croks of the jacquard J escape therefore from the powerof the grate S and not any hole is punched into the cartoon.

Every movement of the jacquard determines the punching of holescorresponding to the teeth of the comb F, which are at this moment incontact with the zone crossed by the current, and by working the commutator D it will be possible to punch separately and successively theholes corresponding to each one of the Zones contained in the design.

At the present time the design is executed on a metallic surface with aninsulating-varnish. All teeth ofythe comb which meet the metallicsurface transmit the current to their corresponding electromagnets andactuate the corresponding punches for striking out the card. All partsof the design situated on the line of the comb are thus pierced onasingle pattern-card. This method can serve only in the execution ofadesign ofone color. Now the designs comprise in general differentcolors or different weft effects which cannot be produced by-a singleweft passage and which require as many pattern-cards as there are colorsor different effects. My-new card v serves the purpose of successivelypunching \Vithout disturbing the comb the record-zone then takes theplace of the first one in the circuit and a new pattern-card is piercedin accordance with the effects of this second zone, and so on. p

The transmission of movement of the electros to the needles of thejacquard, of the needles to the punches, and of the mechanical movementsactuating the machine are of common knowledge.

Referring to Fig. 2, A is the sheet of tin stuck on a non-conductingsupport. \Vhen the design is transferred in reverse on that sheet, thedifferent colors are separated by small traces or furrows a a, in whichthe metal is taken out. Assuming three colors indicated by the letters ZZ Z and shown by section-lines in different directions to distin- {wishthem, asthe color Z is distributed over three insulated zones thesethree zones are connected under the card by a metallic wire and broughttogether at the key I of the commutator. As the colors Z and Z make uponly one zone each,they are con nected,respectively, to the keys 1 and 1The body of the comb F is of non-conducting material. Its metallic teethareinsulated from each other,

and each is connected with one of the electromagnets E, which act uponthe jacquardneedles. These electromagnets are, moreover, connected toone of the poles of the battery P, the other pole being connected withthe switch D. Therefore the current passes only through the teeth whichrest on the color corresponding with the key in contact with the switchD.

Having now described my invention, what Iclaim as new, and desire tosecure by Letters Patent, isf In combination, a card divided intometallic Zones representing different colors insulated from each otherand each zone representing wefts of the same color or nature, circuitconnections and switch means to place the zones separately andsuccessively into the electric circuit, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

TONY DAVID.
